I have been thinking to go back to my roots, and do some really geeky things. One of these things is that I want to create fun multiplayer level for Doom 2. After browsing around for a while, I found Skulltag, and now I'm wondering what is the best way to create levels if I want to use new features of Zdoom / Legacy engine? Back in the day, I made levels using Doom Construction Kit, but that hasn't been updated for years. Something similar would be nice.
